Induction Cooker vs. Electric Stove: Which is More Energy Efficient? - Megafurniture

Induction Cooker vs. Electric Stove: Which is More Energy Efficient?

Are you torn between an induction cooker and its electric counterpart? 

Trust us, you're in good company. The 'induction cooker vs. electric cooker' debate isn't just an ordinary debate in the culinary world. It's also about the watts and kilowatts they pull from your wall. 

The energy they use is a big deal, especially considering those monthly bills and our collective push towards greener choices. 

So, why does this energy tug-of-war matter? Let's unpack it together.

Induction Cooker vs. Electric Stove: How Are They Different?

Electric Induction Stove or Cookers

They harness the power of electromagnetic waves to heat your pots and pans directly. When activated, they send out these waves, which interact with your ferrous cookware, like certain stainless steel or cast iron, making them hot. The magic? The cooker's surface stays relatively chilly.

Electric Stoves

They rely on electric resistance. Flip one on, and electric currents dance through its coils or burners, warming them up. You then set your pot or pan atop these glowing elements to whip up your meal. They're versatile, accommodating a range of cookware, but they might ask for more patience to reach their peak heat than their induction buddies.


Difference on Power Consumption Rates Between Induction Cooker and Electric Stove

There's more to the induction stove vs electric stove debate than their operating nature, let's see how they fare with energy saving.

How Energy Efficient are Induction Cookers?

Typically, induction cookers are more energy-efficient, with about 84-90% of the energy consumed directly transferred to the cookware. This means faster heating and less wasted energy.


Energy Consumption of Electric Stoves

Electric stoves generally have an energy efficiency rate of 74-77%. This means that a portion of the energy is lost to the surrounding environment before it reaches the cookware.

What Are The Cost Implications?

Induction Cookers: While the initial cost of an induction cooker might be higher, the savings in energy bills over time can offset this. The precise savings will depend on local electricity rates and usage patterns.

Electric Stoves: Electric stoves might have a lower upfront cost, but their slightly lower energy efficiency could lead to higher electricity bills over the long run, mainly if used frequently.


Long-term Cost Analysis Based on Power Consumption:

Energy Efficiency

Induction Cookers: Approximately 84-90% energy efficient.

Electric Stoves: Approximately 74-77% energy efficient.


Average Power Consumption

Induction Cookers: Let's assume an average power rating of 1.8 kW.

Electric Stoves: Assume an average power rating of 2 kW.

Usage Scenario

Cooking 1 hour daily for a year: 365 hours/year.

Annual Energy Consumption:

Induction Cookers: 1.8 kW x 365 hours = 657 kWh/year.

Electric Stoves: 2 kW x 365 hours = 730 kWh/year.

Cost Implications (assuming an average electricity rate of $0.12/kWh)

Induction Cookers: 657 kWh x $0.12 = $78.84/year.

Electric Stoves: 730 kWh x $0.12 = $87.60/year.

Over 10 years

Induction Cookers: $78.84 x 10 = $788.40

Electric Stoves: $87.60 x 10 = $876.00

Additional Considerations

Upfront Costs: Induction cookers generally have a higher initial cost than electric stoves. However, over a decade, the difference in energy bills can offset this initial price difference.

Cost of Induction Stove:  4-stove induction hob ranges from $1,400 to $2,000, which is significantly higher compared to a 4-stove gas hob that costs between $700 and $1,000. [please note that this is just an estimated average cost, thus, the actual cost may vary based on brand, model, features, etc.]

Maintenance Costs: Electric stoves might require occasional replacement of coils or burners, while induction cookers have fewer parts that wear out.

Cookware Costs: Induction cookers require specific cookware, which might be an added expense if you still need to own compatible pots and pans.

Environmental Impact

Environmental Impact

Induction Cookers

  • Induction cookers shine regarding direct energy use, channelling about 84-90% of their power straight to your pots and pans. This precision means fewer emissions, especially if your power isn't from green sources.
  • Their knack for rapid heating saves time and trims down overall energy use.
  • One of the unsung perks of induction cooking? Less heat spilling into your kitchen, which can mean less reliance on cooling systems when the mercury rises.
  • The induction cooker energy saving is more significant compared to electric stoves, making them an eco-friendly choice for modern kitchens.

Electric Stoves

  • Electric stoves, while reliable, tend to be more generous with their energy, spreading around 74-77% to the cookware and letting the rest escape. This can mean a slightly heftier carbon footprint if you're plugged into non-renewable grids.
  • These stoves can make your kitchen toastier, potentially nudging you to crank up the AC in hot seasons.


Induction Cooker and Electric Stove Energy Conservation Tips

Induction Cooker and Electric Stove Energy Conservation Tips

Induction Cookers

Right Cookware: Use flat-bottomed and ferrous (magnetic) cookware. The better the pot or pan's base contacts the induction surface, the more efficiently it will heat.

Size Matters: Match the size of your cookware to the size of the burner. Using a small pot on a large burner wastes energy.

Pre-Planning: Since induction cookers heat up rapidly, have all your ingredients ready before turning them on.

Monitor Cooking: Induction cookers cook food faster. Keep an eye on your food to avoid overcooking and wasting energy.

Residual Heat: Turn off the cooker a few minutes before your food is fully cooked. The residual heat will continue to cook the food without consuming more energy.

Electric Stoves

Flat-Bottomed Cookware: Ensure your pots and pans have flat bottoms. This ensures maximum contact with the heating element, leading to faster and more efficient cooking.

Lid On: Keeping a cap on your pots and pans retains heat, speeding up cooking times and conserving energy.

Coil Cleanliness: Keep the stove's coils or burners clean. Dirt and grime can absorb heat, making the stove work harder.

Use the Right Burner: Like with induction, match your pot size to the burner size. A small pot on a large burner means a lot of wasted heat.

Preheat Wisely: If boiling water or heating a pan, start with high heat to reach the desired temperature quickly, then reduce to maintain it.

Utilise Residual Heat: Electric stoves retain heat for a while after being turned off. You can turn off the stove earlier and let the residual heat finish the cooking.

General Tips for Both

Regular Maintenance: Ensure your cooker or stove is in good working condition. A malfunctioning appliance can consume more energy.

Cook in Batches: If you have multiple dishes to prepare, cook them one after the other to take advantage of the heated cooktop.

Thaw Before Cooking: Thaw frozen foods before cooking. This reduces the amount of energy required to heat the food.

Efficient Cooking Methods: Opt for methods like steaming or pressure cooking, which are faster and consume less energy than boiling or baking.

Key Takeaway: 

Are you pitting induction cookers against electric stoves in the energy-saving arena? Induction cookers come out ahead. Their secret? Using electromagnetic magic to heat your pots and pans directly reduces cooking time and energy slips. However, popular and reliable electric stoves need to match that efficiency level. We at Megafurniture think that Induction might be your kitchen MVP if you aim to be an energy-conscious chef.
